How to Clean an Espresso Machine: The Ritual That Keeps It Alive for Years

Well, the marketing says a quick rinse and a wipe-down keeps your espresso machine in fighting shape. Is it really that simple? I've been pulling shots on my Breville Barista Express since 2015, and after nine years, one solenoid valve replacement, and a shoebox full of o-rings, I can tell you the truth: cleaning is the whole ballgame. The ritual is the difference between a machine that lasts nine years and a paperweight that dies at two. Here's exactly what I do, what I use, and what I've learned the hard way.

Product	Price	Why it won	Why it lost
Urnex Cafiza Espresso Machine Cleaning Tablets - 100 Count	$17.99	The industry standard, 100 tablets last me over a year, and it actually dissolves the coffee oils that make shots taste sour.	The packaging is boring and it's not fancy, but that's the only knock I have.
ACTIVE Espresso Machine Cleaning Tablets Descaling - 120 Tabs	$20.95	Great value for 120 tabs, and they work fine for backflushing.	Slightly slower to dissolve than Cafiza, and I had to double-check the concentration for my machine.
Breville BEC250 Espresso Machine Cleaning Tablets, 8 Pack	$11.98	Convenient if you own a Breville and want the exact OEM part.	The price per tablet is highway robbery compared to the bulk options.
Coffee Machine Cleaner Descaler Tablets - 24 Count	$20.95	A decent dual-purpose tablet if you want one product for cleaning and descaling.	I prefer dedicated products; combining both jobs means neither is done perfectly.
Espresso Machine Cleaning Tablet Coffee Maker Cleaner Blister 16tab	$3.79	It's cheap, and it'll get the job done in a pinch.	The blister pack is wasteful, and the tablets are small, so I used two per backflush.

How I Tested the Cleaning Ritual

I'm not a lab tester. I'm the guy who has owned the same Breville BES870XL since 2015, used it every single day, and followed the cleaning guide religiously. My dog Gus, a 65-pound lab mix, sleeps on the mat in front of the machine while I pull my morning shots. He doesn't care about the difference between a $500 machine and a $3,000 one, but he does care that I'm in the kitchen for ten minutes every morning. That's the energy I bring to this.

I ran each of these cleaning products through my real routine: backflushing with a blind basket, wiping down the grouphead, and descaling on schedule. I've also opened the machine up once to replace a solenoid, so I know what a clean grouphead actually looks like inside. That's the standard I'm holding these tablets to.

The Daily Non-Negotiables

Before we get to the tablets, let's talk about the daily stuff, because that's where most people fail. Wipe the steam wand, purge it, wipe it again. Pull a blank shot through the showerhead to clear out any loose grounds. Do not let the water run out. Ever. I've said it before and I'll say it again, because the number of people who ignore this and then complain their machine buzzes is too high. It's not the machine, it's you.

The clean me light is not a suggestion, it's a warning. When it comes on, you backflush. I use Urnex Cafiza tablets for this, and I've tried cheaper alternatives and regretted it. The cheap ones leave a residue that makes the next shot taste like soap, and that's a worse problem than the coffee oils you were trying to clean.

Urnex Cafiza Espresso Machine Cleaning Tablets - 100 Count

I'll lead with the one thing that bugs me: the tablets are small and they dissolve fast, so if you're not paying attention, you'll think you didn't use enough. But that's a me problem, not a product problem. These are the gold standard for a reason.

The 100-count bottle at $17.99 works out to about 18 cents per backflush. I backflush every week, sometimes twice a week if I'm pulling a lot of shots, and one bottle lasts me well over a year. The active ingredient, Cafiza, is the same stuff used in commercial shops, and it dissolves the coffee oils that make shots taste bitter and sour. I've used the Breville OEM tablets and the generic ones, and these are the ones I keep coming back to.

The way I do it: pop one tablet into the blind basket, lock it into the grouphead, and run a few cleaning cycles until the water runs clear. Then I pull a blank shot to rinse everything out. It takes about five minutes, and it's the single most important thing you can do for your machine beyond the daily wipe-down. I've had my machine for nine years, and the grouphead still looks almost new. That's not luck, that's Cafiza.

ACTIVE Espresso Machine Cleaning Tablets Descaling - 120 Tabs

The main knock on these is that they take a little longer to dissolve than the Cafiza tablets. I noticed it on the first backflush, where I had to run an extra cycle to get the water clear. Not a deal breaker, but worth knowing.

At $20.95 for 120 tablets, the value is tough to beat. That's about 17 cents per tablet, and they work fine for the weekly backflush. The bottle is also resealable, which I appreciate because I don't want a bag of tablets sitting in my shoebox of spare parts.

The one thing I'd flag: these are cleaning tablets, not descaler. Don't confuse the two. I use a separate descaling solution every month, and I wouldn't skip that step just because these are cheap. If you're looking for a budget-friendly option for the weekly ritual, these are solid. If you want the absolute best, stick with Cafiza.

Breville BEC250 Espresso Machine Cleaning Tablets, 8 Pack

The price is the problem here. $11.98 for 8 tablets works out to $1.50 per clean, which is about eight times the cost of the bulk options. That's a lot of money for a tablet that does the same thing as the 18-cent Cafiza.

That said, if you own a Breville and you want the exact OEM part, these are fine. They're formulated for the BES870XL and other Breville machines, and they dissolve cleanly without leaving residue. I used them for the first year I owned my machine, before I figured out the math and switched to the bulk stuff.

My advice: buy these if you're in a pinch and you can't wait for shipping. Otherwise, get the Cafiza 100-count and save yourself the money. The machine doesn't care what brand the tablet is, it just needs the coffee oils gone.

Coffee Machine Cleaner Descaler Tablets - 24 Count

I'm lukewarm on this one, and I'll tell you why. It tries to do two jobs at once, and I don't think it does either one perfectly. The cleaning action is fine, but the descaling power is weaker than a dedicated descaler. For $20.95 for 24 tablets, you're paying a premium for a compromise.

If you're the kind of person who wants one product to handle everything, this is a reasonable choice. But I've been doing this for nine years, and I've learned that dedicated products do their job better. I use Cafiza for cleaning and a liquid descaler for the boiler. It's more products to keep track of, but the machine runs better and lasts longer.

The other issue: the tablets are a bit larger, and I found they left a slight residue on the grouphead if I didn't rinse thoroughly. I fixed that by running an extra blank shot, but it's an extra step I don't need.

Espresso Machine Cleaning Tablet Coffee Maker Cleaner Blister 16tab

At $3.79 for 16 tablets, this is the cheapest option on the list, and it's fine for a one-off clean. But I have two complaints. The blister pack is wasteful, and the tablets are small enough that I used two per backflush. That cuts the value in half and makes it about the same cost as the Cafiza.

I bought these once when I was traveling and needed a quick clean. They worked, but I wouldn't make them my daily driver. If you're on a tight budget and you just need to get through a few weeks, these will do. But the bulk options are a better long-term play.

The Monthly Descale

The cleaning tablets handle the coffee oils, but the descale is a separate beast. Mineral buildup in the boiler and lines will kill your machine faster than anything else, and I've seen it happen to friends who ignored the schedule. I use a liquid descaler every month, and I follow the instructions to the letter. Do not let the water run out. Ever.

The descale takes about 30 minutes, and it's a pain. But it's the difference between a machine that lasts nine years and one that dies at two. I've done it every month for nine years, and my machine still pulls a better shot than machines twice the price. That's not luck, that's maintenance.

The Grinder Angle

Here's a thing nobody talks about: the grinder matters as much as the machine, and a clean machine won't save you from a dirty grinder. I wipe out the burr chamber every few weeks and run a few grams of fresh beans through to clear out the old grounds. Stale beans are the enemy, and a clean grinder is the first defense.

The BES870XL has a built-in burr grinder, and it's a big reason the machine is a good value. But the grind amount knob doesn't go low enough on the double setting, so I adjust my dose to match. It's a quirk, not a deal breaker.

Choose the Ritual That Sticks

Here's the honest bottom line: the best cleaning product is the one you'll actually use. If you're the kind of person who wants a simple routine, buy the Cafiza 100-count and backflush weekly. If you're on a budget, the ACTIVE tablets are a fine alternative. But if you're not going to backflush at all, none of this matters. The machine will die, and you'll blame the brand, and I'll be here with my nine-year-old Breville wondering what you did wrong.

I don't track prices day to day, so I won't pretend to know next week's. But I know what works, and I know what has kept my machine alive for nine years. Do the ritual. Descale on schedule. Do not let the water run out. Ever. That's the whole secret.
